Scientists in Argentina have created the world’s first cow to boast two human genes that will enable it to produce human-like milk.
Genetic engineering was used to introduce the “mothers’ milk” genes into the animal before birth, according to the National Institute of Agribusiness Technology in Buenos Aires.
As an adult the cloned cow “will produce milk that is similar to humans” in what will prove “a development of great importance for the nutrition of infants”, it said in a statement.
“The cloned cow, named Rosita ISA, is the first bovine born in the world that incorporates two human genes that contain the proteins present in human milk,” the statement said.
In April scientists in China published details of research showing that they had created GM Holstein dairy cows which produced milk containing proteins found in human breast milk.
But the Argentine team say the Chinese only introduced one human gene, whereas their research involved two genes meaning the milk will more closely resemble that of humans.
Rosita ISA was born on April 6 and was delivered by Caesarean section ...
... because she weighed around 100lbs, roughly twice the normal weight of Jersey cows.
Adrian Mutto, from the National University of San Martin which worked with the institute, said the human genes introduced were “both proteins that can be expressed only in the mammary gland during lactation.”
“Our goal was to raise the nutritional value of cows’ milk by adding two human genes, the protein lactoferrin, which provides infants with anti-bacterial and anti-viral protection, and lysozyme, which is also an anti-bacterial agent,” he added.
Cristina Kirchner, President of Argentina, said that the scientific institute “makes all Argentines proud.”
She also revealed that she had rejected the “honour” of having the cow named after her.
“They came to tell me that the name is Cristina, but what woman would like to have a cow named after her? It appeared to me to be more appropriate to call it Rosita.”
Eating yogurt and other foods laden with lactic acid may keep your gums from receding and teeth from falling out, Japanese researchers report.
Dr. Yoshihiro Shimazaki and colleagues found that consuming yogurt and lactic acid drinks was significantly associated with better periodontal health.
"But, milk and cheese were not," Shimazaki said.
Periodontal disease is a chronic bacterial condition associated with receding gums and tooth loss. Outside of regular brushing and flossing, effective measures to allay this disease are limited, Shimazaki, of Kyushu University in Fukuoka, Japan, and colleagues note in the Journal of Periodontology.
Previous research identified a lower occurrence of periodontal disease among people who eat high amounts of dairy products, but did not identify which dairy products were most beneficial, the researchers report.
Shimazaki's team assessed the severity of periodontal disease in 942 men and women, aged 40 to 79 years, and their intake of milk, cheese, and lactic acid foods.
They found that people with generalized (more advanced) periodontal disease had a lower intake of lactic acid foods than people with localized (less advanced) periodontal disease.
Compared with individuals reporting no lactic acid food intake, those eating 55 grams or more of yogurt (half an 6-ounce carton) or lactic acid drinks a day had significantly fewer markers of severe periodontal disease. The investigators made allowances for factors such as age, gender, smoking, alcohol intake, frequency of tooth brushing, blood sugar and cholesterol levels.
